TECHNICAL FIELD

The present invention relates to the technical field of application of makeup tools, in particular to a silica gel smudge brush.

BACKGROUND

In today's life, makeup, as a part of office and life etiquette, has become a very common phenomenon. Especially, the use of cosmetics is a very important part of makeup, particularly, the use of eye shadow, when applying cosmetics, can make people's eyes more beautiful.

Currently, eye shadow is applied by means of a sponge smudge brush in the prior art. However, the connection mode for the sponge smudge brush is that a sponge head is connected surfacely to a rod via glue. Moreover, as the sponge has lots of small holes, the eye shadow will enter the sponge head and come into contact with the glue when the sponge is dipped in the eye shadow, thereby the glue is partially brought into the eye shadow and applied to the skin, causing contamination and irritation to the skin.

In summary, the problem in the prior art is that due to the permeability of the sponge, the glue is brought into the eye shadow when the eye shadow comes into contact with the glue, thereby contaminating the skin.

DETAILED DESCRIPTION Example 1

The present example provides a silica gel smudge brush, as shown in FIG. 1, comprising a head portion 100 and a rod portion 200. The head portion 100 comprises a dipping end 110 and a connection end 120, a surface layer of the dipping end 110 is a silica gel material layer for dipping in eye shadow. One end of the rod portion 200 is connected with the connection end 120 of the head portion 100 for holding of the silica gel smudge brush.

The silica gel smudge brush provided in the present example comprises the head portion 100 and the rod portion 200. The rod portion 200 is hold by a hand so that the head portion 100 is dipped in eye shadow and then applies the eye shadow to the skin. As the surface layer of the dipping end 110 is silica gel material layer, the eye shadow can be adsorbed and will not permeate into the silica gel material layer. Therefore, the silica gel smudge brush solves the technical problem in the prior art that due to the permeability of sponge, the glue is brought into the eye shadow when the eye shadow comes into contact with the glue, thereby contaminating the skin.

Since silica gel has adsorption effect and the softness of the head portion is close to that of sponge, the above technical problem in the prior art can be solved.

In a specific production process, considering the problems that complex production and assembly processes of the sponge smudge brushs, for example complicated procedures required by the sponge smudge brush such as foaming, hot pressing, bevelment of the eye shadow head, and bonding with glue, increase the production cost; the sponge smudge brushs have defects of low assembling yield, large number of working procedures, manually assembly, high defect rate; and the sponge smudge brush can hardly be automatically produced due to the material and process requirements, the following solution is put forward.

The head portion 100 and the rod portion 200 are both made of silica gel material and are integrally formed.

In the specific application process of the silica gel smudge brush, since silica gel is relatively softer, the strength for holding the rod portion made of silica gel material is not enough. In order to solve this technical problem, the silica gel smudge brush further comprises a holding tube 300, as shown in FIG. 4, which is sleeved on an outer side wall of the rod portion 200 in a direction of an extension line of the rod portion 200, and is in a fixed position relative to the rod portion 200.

As the holding tube 300 is sleeved on the outer side wall of the rod portion 200, in order to fix the holding tube, in a length direction of the rod portion 200, the outer side wall of one end of the rod portion 200 close to the head portion 100 a is provided thereon with a barb 210, as shown in FIG. 2. The holding tube 300 is arranged in the barb 210.

One end of the rod portion 200 away from the head portion 100 is of a truncated cone shape, in which one end of the truncated cone shape structure away from the barb 210 is of a first smaller surface 220, and one end of the truncated cone shape structure close to the barb 210 is of a first larger surface 230. The holding tube 300 is of a truncated cone shape, in which one end of the holding tube 300 away from the head portion 100 is of a second smaller surface 310, and one end of the holding tube close to the head portion 100 is of a second larger surface 320. A radius of the second smaller surface 310 is greater than a radius of the first smaller surface 220, and is smaller than a radius of the first larger surface 230. A radius of the second larger surface 320 is greater than the radius of the first larger surface 230.

As shown in FIG. 5, the process of mounting the holding tube 300 onto the silica gel smudge brush is as follows.

Silica gel is soft, stretchable and diminishable, and the rod portion is designed with the barb in the middle thereof, at the time of assembly, the silica gel is stretched so that the holding tube successfully enters the corresponding barb position. This results from that the holding tube 300 has the second smaller surface 310 and the second larger surface 320, when the first smaller surface 220 of the rod portion 200 enters the second larger surface 320 and subsequently passes through the second smaller surface 310, as the radius of the second smaller surface 310 is greater than the radius of the first smaller surface 220 and smaller than the radius of the first larger surface 230, the second smaller surface 310 of the holding tube 300 is snapped with the middle of the rod portion 200, moreover, as the radius of the second larger surface 320 is greater than the radius of the first larger surface 230, the holding tube 300 can pass via stretching the rod portion 200 to make the rod portion thinner.

When the holding tube is assembled in place, as there is no tension, the silica gel is retracted to a natural state for jamming into the holding tube 300, so that the holding tube 300 fits tightly with the rod portion 200 made of silica gel, without applying any glue to achieve the assembly of the above two components.

When the holding tube 300 enters the barb 210, if the diameter of the silica gel of the barb 210 is greater than the width of the holding tube 300, a relatively large pressure will be applied to the holding tube 300, which may cause break of the joint of the holding tube 300. In order to avoid this problem, the barb 210 is provided therein with a ridge 211 in the length direction of the rod portion 200.

A chamfer 330 is provided on an outer side ridge at one end of the holding tube 300 away from the head portion 100, which is configured for preventing sharp edges or corners of the holding tube 300 from scraping the skin.

Example 2

The present application provides a silica gel smudge brush, in which one end of the rod portion 200 away from the head portion 100 is further provided with another head portion 100. The holding tube 300 is sleeved on the rod portion 200 and is assembled between the two head portions 100 in a position-limited manner. Moreover, the another head portion 100 is also made of silica gel material.

The two head portions 100 are both made of silica gel material, which do not have permeability, but have certain adsorbability and can be dipped in cosmetics. Thus, the technical problem in the related art, that glue permeates into the silica gel smudge brush and contaminates the skin, is solved.

The two head portions 100 can have the same or different shapes and sizes. In the present example, as shown in FIG. 7, one head portion 100 is larger than the other head portion 100. One of the head portions 100 has a relatively larger tip angle, which looks more smooth and rounded, so as to draw relatively thicker lines, and the other head portion 100 has a relatively smaller tip angle, which looks sharper, so as to draw relatively thinner lines.

The holding tube 300 has a hollow tubular shape, and has a length smaller than that of the rod portion 200. Since the holding tube needs to be held in the makeup process, it is better that the weight thereof is as small as possible. Preferably, the holding tube 300 is made of metal aluminum.

The holding tube 300 is position-limited to locate between the two head portions 100. The silica gel smudge brush further comprises a position limiting unit configured for limiting a relative position between the assembled rod portion 200 and holding tube 300.

In specific practice, there are multiple methods for assembling the holding tube 300 with the rod portion 200. Different assembly methods are used according to different needs, and the assembly methods are specifically described as follows.

First Type:

The holding tube 300 is in interference fit with the rod portion 200. The position limiting unit comprises a first protrusion 240 provided on an outer side wall of the rod portion 200 and a position limiting structure provided on a side wall of the holding tube 300, and the first protrusion 240 is snapped with the position limiting structure.

Interference fit: an outer diameter of the rod portion 200 is greater than an inner diameter of the holding tube 300. As the rod portion 200 is made of silica gel material and has certain elasticity, after the holding tube 300 is sleeved on the rod portion 200, the rod portion 200 applies an expansion force to the holding tube 300 after being elastically deformed. The expansion force and a frictional force of the silica gel per se prevent the movement of the holding tube 300 relative to the rod portion 200.

The first protrusion 240 is located on the outer side wall of the rod portion 200, and the first protrusion 240 is also made of silica gel material. Preferably, the first protrusion 240 and the rod portion 200 are integrally formed.

The first protrusion 240 and the second protrusion 330 are configured to correspond to each other and have a same protruding direction, and the first protrusion 240 is snapped with the second protrusion 330.

As shown in FIG. 8, the first protrusion 240 is located on the outer side wall of the rod portion 200. For the sake of more effective snapping of the first protrusion 240 into the second protrusion 330 and prevention of a relative movement, caused by dislocation of snapping, etc., between the rod portion 200 and the holding tube 300, the first protrusion 240 is located in the middle portion of the outer side wall of the rod portion 200, and the number of the first protrusions is not limited.

The first protrusion 240 and the second protrusion 330 protrude towards the same direction. Preferably, both of them protrude towards the direction away from the axis of the rod portion 200 and are perpendicular to the axis of the rod portion 200.

The first protrusion 240 and the position limiting hole 340 correspond to each other in the position, and the first protrusion is snapped with the position limiting hole 340.

In order to achieve stability of snapping the first protrusion 240 with the position limiting hole 340, the first protrusion 240 is located in the middle portion of the outer side wall of the rod portion 200. Moreover, the first protrusion 240 is a boss and the shape thereof is not limited. Preferably, the first protrusion 240 is oval, and the length direction of the oval coincides with the length direction of the rod portion 200.

INDUSTRIAL APPLICABILITY

For the silica gel smudge brush described above, since silica gel is used as the material of the head portion, the head portion has the softness close to that of sponge, has the surface with certain adsorbability on powder particles and also has an ideal effect on the paste-like cosmetic, which will not be adsorbed into silica gel to cause waste. Moreover, in terms of environmental protection and non-toxicity, the silica gel is much better than the sponge. In terms of product lifetime, the silica gel is more acid-alkali resistant than the sponge and is also more corrosion-resistant than the sponge, therefore, the service life of the silica gel is ten or more times that of the sponge material in the same state. In terms of sanitation, the silica gel can be cleaned just by rinse with water after use, can be easily dried after rinse, and can be put into a cosmetic box immediately after wash, wipe and dry, since water cannot enter the silica gel, it is very difficult to generate bacteria. On the contrary, as for the sponge material, powders can enter the holes of the sponge, which will hardly be cleaned by rinse, and if the sponge were rinsed, it takes a relatively longer time to get dried and it is also difficult to dry it by baking, while if sponge were not washed or were not cleaned the bacteria can easily grow, which will cause damages to the skin. And in terms of smudge with mottle, during the makeup process, a single sponge stick will be dipped in makeup powders with different colors. As the makeup powders enter the small holes of the sponge, the residuals can hardly come out after applying the makeup powders to the sponge, and the sponge stick can hardly be cleaned with a tissue when the makeup powder with another color needs to be used, thereby causing smudge. For example, when a makeup powder with blue is applied first and then a makeup powder with red is applied, finally a mixed color with blue and red will be rendered. While for the silica gel, color exchange can be achieved without any smudge just by wiping the residuals from the surface with a tissue, and the desired color can be got easily, as the silica gel does not adsorb makeup powders.

In accordance with common practice, the various features illustrated in the drawings may not be drawn to scale. The illustrations presented in the present disclosure are not meant to be actual views of any particular apparatus (e.g., device, system, etc.) or method, but are merely idealized representations that are employed to describe various embodiments of the disclosure. Accordingly, the dimensions of the various features may be arbitrarily expanded or reduced for clarity. In addition, some of the drawings may be simplified for clarity. Thus, the drawings may not depict all of the components of a given apparatus (e.g., device) or all operations of a particular method.

Terms used herein and especially in the appended claims (e.g., bodies of the appended claims) are generally intended as “open” terms (e.g., the term “including” should be interpreted as “including, but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes, but is not limited to,” etc.).

Additionally, if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases “at least one” and “one or more” to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to embodiments containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “a” and/or “an” should be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce claim recitations.

In addition, even if a specific number of an introduced claim recitation is explicitly recited, it is understood that such recitation should be interpreted to mean at least the recited number (e.g., the bare recitation of “two recitations,” without other modifiers, means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc.” or “one or more of A, B, and C, etc.” is used, in general such a construction is intended to include A alone, B alone, C alone, A and B together, A and C together, B and C together, or A, B, and C together, etc. For example, the use of the term “and/or” is intended to be construed in this manner.

Further, any disjunctive word or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase “A or B” should be understood to include the possibilities of “A” or “B” or “A and B.”

Additionally, the use of the terms “first,” “second,” “third,” etc., are not necessarily used herein to connote a specific order or number of elements. Generally, the terms “first,” “second,” “third,” etc., are used to distinguish between different elements as generic identifiers. Absence a showing that the terms “first,” “second,” “third,” etc., connote a specific order, these terms should not be understood to connote a specific order. Furthermore, absence a showing that the terms first,” “second,” “third,” etc., connote a specific number of elements, these terms should not be understood to connote a specific number of elements. For example, a first widget may be described as having a first side and a second widget may be described as having a second side. The use of the term “second side” with respect to the second widget may be to distinguish such side of the second widget from the “first side” of the first widget and not to connote that the second widget has two sides.
